La estrategia es un sistema comercial integral que combina el algoritmo de aprendizaje automático K-nearest neighbor (KNN), reconocimiento de patrones de velas y análisis de volumen. La estrategia forma un marco de análisis tridimensional para el mercado a través de métodos de análisis multidimensional, incluidos canales de promedio móvil, verificación de umbral de volumen y estadísticas de probabilidad, capturando así oportunidades comerciales potenciales.
La lógica central de la estrategia se basa en los siguientes elementos clave:
La estrategia construye un sistema comercial sólido combinando el análisis técnico tradicional con métodos modernos de aprendizaje automático. El marco de análisis multidimensional de la estrategia y el estricto mecanismo de confirmación de señales proporcionan una base confiable para las decisiones comerciales. Se espera que mediante la optimización continua y el control de riesgos, la estrategia mantenga un rendimiento estable en diversos entornos de mercado.
